The electronic device includes a display, a fingerprint sensor disposed under the display, and a processor electrically connected with the display and the fingerprint sensor. The processor is configured to set a fingerprint sensing region at a location, which corresponds to a location where the fingerprint sensor is disposed, on the display if the electronic apparatus enters a state for registering a fingerprint of a finger, to display a first guide on the display such that the first guide at least partly overlaps the fingerprint sensing region, to obtain first fingerprint information through the fingerprint sensing region if the finger touches the first guide, to display a second guide on the display such that the second guide at least partly overlaps the fingerprint sensing region, and to obtain second fingerprint information through the fingerprint sensing region if the finger touches the second guide.

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Sep. 20, 2016 in the Korean Intellectual Property Office and assigned Serial number 10-2016-0120280, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a technology that processes user registration and fingerprint information in an electronic apparatus.

BACKGROUND

With the development of technologies recognizing biometric information, an electronic apparatus including a biometric sensor such as a fingerprint sensor, an iris sensor, or the like has been widely distributed. The electronic apparatus may recognize biometric information of a user by using the biometric sensor and may store the biometric information of the user in an internal memory therein. The stored biometric information may be used when the user unlocks a screen or makes a financial transaction (e.g., transferring money, making an electronic payment).

The fingerprint sensor may set a point, at which a fingerprint ridge is divided or broken, to a minutia and may obtain distribution of minutiae, the number of minutiae, or the like from a fingerprint. The fingerprint sensor may determine whether the fingerprint is authenticated, by comparing the distribution of minutiae or the number of minutiae stored in a memory with the distribution of minutiae or the number of minutiae that is newly recognized.

Since the electronic apparatus needs elements such as a display, a printed circuit board (PCB), a battery, and the like in addition to the fingerprint sensor, there may not be enough space for mounting the fingerprint sensor. In addition, in the case where a fingerprint sensor, the size is big, is mounted in the electronic apparatus, the cost of production may increase. Accordingly, there is a need to mount a fingerprint sensor, the size is small, in the electronic apparatus.

If the size of fingerprint sensor is less than the size of a finger, a procedure of recognizing different regions of the finger by using the fingerprint sensor may be repeated to obtain a fingerprint image. Furthermore, in the repeated procedure of recognizing the different regions of the finger, there is a need for the user to properly move a location, a direction, or the like of the finger to obtain the entire fingerprint image of the finger.

However, the user may allow the fingerprint sensor to continuously recognize the fingerprint at the same location. Alternatively, the user may continuously allow the electronic apparatus to continuously recognize the same fingerprint region of the fingerprint. If the user allows the electronic apparatus to continuously recognize a fingerprint at the same location or if the user allows the electronic apparatus to continuously recognize the same fingerprint region, the electronic apparatus may not obtain the entire fingerprint image.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

In this disclosure, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., elements such as numeric values, functions, operations, or components) but do not exclude presence of additional features.

In this disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included.

The terms, such as “first”, “second”, and the like used in this disclosure may be used to refer to various elements regardless of the order and/or the priority and to distinguish the relevant elements from other elements, but do not limit the elements. For example, “a first user device” and “a second user device” indicate different user devices regardless of the order or priority. For example, without departing the scope of the present disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

It will be understood that when an element (e.g., a first element) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element), it may be directly coupled with/to or connected to the other element or an intervening element (e.g., a third element) may be present.

FIG. 1 illustrates an electronic apparatus 100, according to an embodiment of the present disclosure.

Referring to FIG. 1, the electronic apparatus 100 may include a display 106, a bezel 126, and a button 124.

The display 106 may display a guide 502 (or a graphic indicator) so as to at least partly overlap a fingerprint sensing region 122 c. If the display 106 displays the guide 502, a user may touch the guide 502 with his/her finger, and a processor may obtain fingerprint information through a part in which the guide 502 overlaps the fingerprint sensing region 122 c.

In the present disclosure, the guide 502 may be a mark that guides the user to touch the display 106 with his/her finger. The guide 502 is illustrated in FIG. 1 as being in a shape of a fingerprint. However, the form of the guide 502 is not limited in an example illustrated in FIG. 1. The fingerprint sensing region 122 c may be a region that corresponds to a fingerprint sensor 122 a disposed under the display 106. The fingerprint sensing region 122 c may be directly displayed on the display 106 or may not be displayed. A location at which the fingerprint sensing region 122 c is formed may be an active area or a black matrix area of the display 106.

The bezel 126 may be disposed on a side surface of the display 106 and may be coupled with a housing. The bezel 126 may include a non-metal region and may be composed of, for example, a plastic injection mold. Although not illustrated in FIG. 1, a receiver, a proximity sensor, a camera, or the like may be disposed in a partial region of the bezel 126.

The button 124 disposed in the partial region of the bezel 126 may control the electronic apparatus 100. For example, the button 124 may be referred to as a home button, a back button, or a menu button. In the case where the button 124 is a home button, if the user presses the button 124, a home screen may be output through the display 106.

The electronic apparatus 100 is illustrated in FIG. 1 as including the display 106, the bezel 126, and the button 124. However, the electronic apparatus 100 may be of a full front screen form. In the case where the electronic apparatus 100 is of the full front screen form, the display 106 may be disposed on a front surface of the electronic apparatus 100 without the bezel 126 and the button 124.

FIG. 2 illustrates a sectional view of the electronic apparatus 100, according to an embodiment of the present disclosure.

Referring to FIG. 2, the electronic apparatus 100 may further include a cover glass 102, an adhesive 104, structures 108-1 and 108-2, a PCB 110, elastic bodies 112-1 and 112-2, and the fingerprint sensor 122 a.

The cover glass 102 may transmit light generated by the display 106. Also, a user may touch the cover glass 102 with a portion (e.g., a finger) of his/her body to make a touch (including a contact using an electronic pen). The cover glass 102 may be form of, for example, tempered glass, reinforced plastic, a flexible polymer material, or the like and may protect the display 106 or each element included in the electronic apparatus 100 from an external shock. According to an embodiment, the cover glass 102 may be also referred to as a “glass window”.

The adhesive 104 may allow the cover glass 102 and the display 106 to be attached to each other. The adhesive 104 may include a transparent film such that light generated by the display 106 is transmitted. For example, the adhesive 104 may be referred to as an optical clear adhesive film.

The structures 108-1 and 108-2 may be a configuration for securing a space in which the fingerprint sensor 122 a is mounted. According to an embodiment, the structure 108-1 and 108-2 may be referred to as a bracket. The structures 108-1 and 108-2 may be composed of a magnesium alloy and may be physically coupled to the display 106 and the PCB 110 so as to support the display 106 and the PCB 110.

The PCB 110 may be disposed below the structure 108-1 and 108-2 and may be electrically connected with the display 106 and the fingerprint sensor 122 a through a specified connector or specified wiring. For example, the PCB 110 may be implemented with a rigid PCB. According to an embodiment, various electronic components, elements, printed circuits, and the like of the electronic apparatus 100 may be mounted or arranged on the PCB 110.

The elastic bodies 112-1 and 112-2 may be interposed between the fingerprint sensor 122 a and the display 106, and may absorb shock between the display 106 and the fingerprint sensor 122 a. For example, the elastic bodies 112-1 and 112-2 may be formed of sponge, rubber, or the like. The elastic bodies 112-1 and 112-2 may prevent a foreign object from entering the fingerprint sensor 122 a.

The fingerprint sensor 122 a interposed between the display 106 and the PCB 110 may obtain fingerprint information of a finger contacting the display 106. The fingerprint sensor 122 a is illustrated in FIG. 2 as being interposed between the display 106 and the PCB 110. However, the fingerprint sensor 122 a may be disposed in the display 106, and may be interposed between the cover glass 102 and the display 106. The size of the fingerprint sensor 122 a may be less than the size of the display 106 or may be the same as the size of the display 106. In the case where the size of the fingerprint sensor 122 a is the same as the size of the display 106, the electronic apparatus 100 may obtain fingerprint information through the entire region of the display 106.

The number of the fingerprint sensor 122 a may be one, or may be two or more. If the number of the fingerprint sensor 122 a is two or more, the electronic apparatus 100 may obtain fingerprint information in a plurality of regions. The fingerprint sensor 122 a may be an optical image sensor, an ultrasonic sensor, or an electrostatic sensor. The type of the fingerprint sensor 122 a is not limited to the above-described examples.

FIG. 3 illustrates a block diagram of the electronic apparatus 100, according to an embodiment of the present disclosure.

Referring to FIG. 3, the electronic apparatus 100 may include a first processor 114, a second processor 116, a memory 118, the display 106, and a sensor 122.

The first processor 114 may be connected with the memory 118, the display 106, and the sensor 122 to control each of the memory 118, the display 106, and the sensor 122. For example, the first processor 114 may turn on/off the display 106 by using an instruction stored in the memory 118. In the case where the electronic apparatus 100 operates in a low-power mode, the second processor 116 may control each of the display 106 and the sensor 122. For example, if a user touches the display 106 with his/her finger, the second processor 116 may obtain fingerprint information through the fingerprint sensor 122 a. If the user touches the display 106 with an object (e.g., a touch pen), the second processor 116 may sense a location of the object through a touch sensor 122 b.

The memory 118 may store instructions for controlling the display 106, the sensor 122, and the like. According to an embodiment, the memory 118 may include a normal region for storing a user application or the like or a security region for storing information (e.g., information obtained through the fingerprint sensor 122 a) sensitive to security.

The display 106 may include a display driver integrated circuit (DDI) 106 a and a display panel 106 b. The display panel 106 b may include a plurality of pixels. The DDI 106 a may electrically connect a processor with the display panel 106 b. The DDI 106 a may control at least a part of a plurality of pixels included in the display panel 106 b to display an image.

The sensor 122 may include the fingerprint sensor 122 a and the touch sensor 122 b. The sensor 122 may further include an iris sensor that obtains iris information of the user. The fingerprint sensor 122 a obtains fingerprint information of a user. According to an embodiment, the fingerprint sensor 122 a may obtain biometric information by using light irradiated by the display 106. The touch sensor 122 b may sense a location at which the user touches the display 106.

FIG. 4 illustrates an operation flowchart of the electronic apparatus 100, according to an embodiment of the present disclosure. In this disclosure, details described with reference to FIGS. 1 to 3 may be identically applied to elements that have the same reference numerals as those of the electronic apparatus 100 described with reference to FIGS. 1 to 3. A processor may be one of the first processor 114 or the second processor 116 described in FIG. 3.

Referring to FIG. 4, in operation 401, the electronic apparatus 100 may enter a state for registering a fingerprint. For example, the state for registering the fingerprint may be a state where there is no fingerprint information of a user in the memory 118 or a state for updating the fingerprint information of the user. If the electronic apparatus 100 enters the state for registering the fingerprint, in operation 403, the processor may set the fingerprint sensing region 122 c on the display 106. The processor may set a size of the fingerprint sensing region 122 c to be the same as a size of the fingerprint sensor 122 a, and may set the size of the fingerprint sensing region 122 c to be different from a size of the fingerprint sensor 122 a. According to an embodiment, the processor may display the fingerprint sensing region 122 c at a location corresponding to a location, at which the fingerprint sensor 122 a is disposed, on the display 106.

If the processor sets the fingerprint sensing region 122 c, in operation 405, the processor may display the first guide 502 on the display 106 so as to at least partly overlap the fingerprint sensing region 122 c. If the first guide 502 is displayed on the display 106, the user may touch the first guide 502 with his/her finger, in operation 407, the processor may obtain first fingerprint information through the fingerprint sensing region 122 c. According to an embodiment, the processor may obtain the first fingerprint information through a first region 502 a, which the fingerprint sensing region 122 c occupies, in the first guide 502. The first fingerprint information may be fingerprint information obtained through the first guide 502 and may include images, minutiae, distribution of minutiae, or the like of a fingerprint.

If the first fingerprint information is obtained, in operation 409, the processor may set a region for displaying a second guide 504. For example, the processor may set the region for displaying the second guide 504 based on one or more of a location of the first guide 502, an area of the first region 502 a, and the first fingerprint information. If the region for displaying the second guide 504 is set, in operation 411, the processor may display the second guide 504 such that the display 106 at least partly overlaps the fingerprint sensing region 122 c.

If the second guide 504 is displayed on the display 106, the user may touch the second guide 504 with his/her finger, and, in operation 413, the processor may obtain second fingerprint information through the fingerprint sensing region 122 c. According to an embodiment, the processor may obtain the second fingerprint information through a second region 504 a, which the fingerprint sensing region 122 c occupies, in the second guide 504.

In operation 415, the processor may determine whether the obtained fingerprint information is sufficient. For example, the processor may determine whether a fingerprint image, the region of which is not less than a preset region, is obtained. If the region of the obtained fingerprint image is not less than the preset region, the processor may store the minutiae, the distribution of minutiae, or the like of the fingerprint in the memory 118 based on the obtained fingerprint image. If the region of the obtained fingerprint image is less than the preset region, the processor may set a region for a third guide to obtain an additional image. Until the sufficient fingerprint image is obtained through operation 409 to operation 415, the processor may allow the display 106 to display guides.

FIG. 5A illustrates a view in which the first region 502 a and the second region 504 a are at least partly overlapped, according to an embodiment of the present disclosure. FIG. 5B illustrates a view in which the second guide 504 is displayed on a display 106 based on first fingerprint information, according to an embodiment of the present disclosure. FIG. 5C illustrates a view in which the second guide 504 is displayed on a display 106 such that a region missed in the first fingerprint information is obtained, according to an embodiment of the present disclosure. FIG. 5D illustrates a view in which a second guide is displayed on a display based on a slope of a first guide, according to an embodiment of the present disclosure. FIG. 5E illustrates a view in which a second guide is displayed on a display based on a contact region, according to an embodiment of the present disclosure. Embodiments illustrated in FIGS. 5A to 5E may be examples of operation 409 for setting an additional guide (e.g., the second guide 504).

Referring to FIG. 5A, the first region 502 a, which the fingerprint sensing region 122 c occupies, in the first guide 502 and the second region 504 a, which the fingerprint sensing region 122 c occupies, in the second guide 504 may be set to be at least partly overlapped with each other. A region (hereinafter referred to as an “overlapped region”) in which the first region 502 a overlaps the second region 504 a is illustrated in FIG. 5A as being in a boundary of the fingerprint sensing region 122 c. However, the overlapped region may be in the center of the fingerprint sensing region 122 c. In addition, the overlapped region is illustrated in FIG. 5A as being a part of the fingerprint sensing region 122 c. However, the overlapped region may include the entire fingerprint sensing region 122 c. According to an embodiment of the present disclosure, second fingerprint information associated with first fingerprint information may be obtained by being set such that the first region 502 a and second region 504 a are at least partly overlapped with each other.

According to an embodiment, a processor may allow the display 106 to display the second guide 504 based on a location of the first guide 502. For example, if the first guide 502 is displayed in a region moving from the fingerprint sensing region 122 c in a fourth direction, the second guide 504 may be displayed in a region moving from the first guide 502 in a second direction. If the first guide 502 is displayed in a region moving from the fingerprint sensing region 122 c in a first direction, the second guide 504 may be displayed in a region moving from the first guide 502 in a third direction.

Returning to FIG. 5A, the first guide 502 may be displayed on the display 106, and the processor may obtain the first fingerprint information through the first guide 502. If the first fingerprint information is obtained, the first guide 502 may disappear on the display 106. If the first guide 502 disappears, the second guide 504 may be displayed on the display 106, and the processor may obtain the second fingerprint information through the second guide 504.

Unlike the above-described embodiment, the first guide 502 and the second guide 504 may be simultaneously displayed on the display 106. According to an embodiment, the processor may differentiate and display the first guide 502 and the second guide 504 by using a brightness difference between the first guide 502 and the second guide 504. For example, the first guide 502 may be displayed to be relatively bright, and the second guide 504 may be displayed to be relatively dark. If a fingerprint is recognized through the first guide 502, the processor may display the first guide 502 to be darker or may not display the first guide 502, and the processor may display the second guide 504 to be brighter. In this way, the processor may guide the user to sequentially recognize the fingerprint through an appropriate guide. The processor may differentiate the first guide 502 and the second guide 504 by displaying the first guide 502 and the second guide 504 in different shapes. The criteria for differentiating the first guide 502 and the second guide 504 is not limited to the above-described examples.

Referring to FIG. 5B, the processor may allow the display 106 to display the second guide 504 based on the first fingerprint information. For example, as illustrated in FIG. 5B, if the first guide 502 is displayed in a region moving from the fingerprint sensing region 122 c in the second direction, the processor may obtain a part of a left region of a fingerprint of a finger. Accordingly, to obtain a part of a right region of the fingerprint of the finger through the second guide 504, the second guide 504 may be displayed in a region moving from the first guide 502 in the fourth direction. If the second guide 504 is displayed in a region moving from the first guide 502 in the fourth direction, the processor may obtain a part of the right region of the fingerprint of the finger as well as a part of the left region of the fingerprint of the finger.

The second guide 504 is illustrated in FIG. 5B as being displayed in a region moving from the first guide 502 in the fourth direction. However, the second guide 504 may be disposed in a region moving from the first guide 502 in the first direction, the second direction, or the third direction. For example, if the first guide 502 is displayed in a region moving from the fingerprint sensing region 122 c in the first direction, the processor may obtain a part of a lower region of a fingerprint of a finger. Accordingly, to obtain a part of an upper region of the fingerprint of the finger through the second guide 504, the second guide 504 may be displayed in a region moving from the first guide 502 in the third direction.

Referring to FIG. 5C, the processor may obtain a region 502 b that is missed in the first fingerprint information and may allow the display 106 to display the second guide 504 based on the region 502 b. In the embodiment of FIG. 5C, the first fingerprint information may correspond to fingerprint information that is obtained up to now by a guide provided at least one or more times. For example, the processor may compare a fingerprint region to be obtained with the first fingerprint information to obtain the region 502 b missed in the first fingerprint information. The fingerprint region to be obtained may be information stored in the memory 118, and the first fingerprint information may be information obtained from the first guide 502.

If the region 502 b missed in the first fingerprint information is obtained, the processor may display the second guide 504 on the display 106 such that the region 502 b is included. For example, the region 502 b may be included in the second region 504 a that the fingerprint sensing region 122 c occupies in the second guide 504. According to an embodiment of the present disclosure, various fingerprint regions may be obtained by displaying a guide so as to include the missed fingerprint region.

Referring to FIG. 5D, the processor may allow the display 106 to display the second guide 504 based on a slope of the first guide 502. For example, in FIG. 5D, the first guide 502 may be tilted and displayed between the first direction and the second direction. If the first guide 502 is tilted and displayed, the processor may obtain a part of a lower left region of the fingerprint of the finger. Accordingly, to obtain a part of a lower right region of the fingerprint of the finger through the second guide 504, the processor may obliquely display the second guide 504 between the first direction and the fourth direction. If the second guide 504 is tilted and displayed between the first direction and the fourth direction, the processor may obtain a part of a lower right region of the fingerprint of the finger as well as a part of a lower left region thereof.

The slopes of the first guide 502 and the second guide 504 are not limited to the embodiment illustrated in FIG. 5D. For example, the first guide 502 and the second guide 504 may be inclined in another direction. For example, the first guide 502 may be tilted and displayed between the second direction and the third direction. If the first guide 502 is tilted and displayed between the second direction and the third direction, the processor may obtain a part of an upper left region of the fingerprint of the finger. Accordingly, to obtain a part of an upper right region of the fingerprint of the finger through the second guide 504, the processor may display the second guide 504 to be inclined between the third direction and fourth direction.

Referring to FIG. 5E, the processor may allow the display 106 to display the second guide 504 based on a touch input information. The touch input information may include a size, a location, an angle, or the like of a region 508 that the user touches in the display, and may be information obtained by a touch sensor.

In FIG. 5E, the processor may display the first guide 502 in the display. If the first guide 502 is displayed in the display, the user may touch the display with his/her finger. If the finger touches the display, the processor may display the second guide 504 in the display based on the touch input information. For example, if the size of the region 508 that the user touches in the display is greater than the size of the first guide 502, the processor may display the size of the second guide 504 in the display to be greater than the size of the first guide 502. The size of the region 508 that the user touches in the display may be proportional to the size of the finger, and may be less than the size of the first guide 502. If the size of the region 508 that the user touches in the display is less than the size of the first guide 502, the processor may display the size of the second guide 504 in the display to be less than the size of the first guide 502.

In addition, the processor may display the second guide 504 in the display based on the location of the region 508 that the user touches in the display. For example, as illustrated in FIG. 5E, the location of the region 508 that the user touches in the display may be in a region that moves from the first guide 502 in the first direction. The processor may display the second guide 504 in a region, which moves from the first guide 502 in the third direction, based on the first guide 502 and the location of the region 508 that the user touches in the display. If the second guide 504 is displayed in a region that moves from the first guide 502 in the third direction, the user may touch the center of the fingerprint sensing region 122 c with his/her finger.

According to an embodiment of the present disclosure, the processor may display the second guide 504 based on the touch input information, and may display the second guide 504 based on the touch input information and the first fingerprint information. For example, as illustrated in FIG. 5E, if the finger touches a display, a part of a lower region of the fingerprint of the finger may be obtained. Moreover, in FIG. 5E, the size of the region 508 that the user touches in the display may be greater than the size of the first guide 502. Accordingly, to obtain a part of an upper region of the fingerprint such that a guide suitable for the size of the finger is displayed, the processor may display the second guide 504, the size of which is greater than the size of the first guide 502, in a region moving from the fingerprint sensing region 122 c in the third direction.

In the embodiments illustrated in FIGS. 5A to 5E, a memory may store a guide of a default form, and the processor may change the guide of the default form stored in the memory and may display the changed guide in the display. For example, Referring to FIG. 5D, after displaying the guide of the default form to be inclined between the first direction and the second direction, the processor may display the guide of the default form to be inclined between the first direction and the fourth direction.

According to an embodiment of the present disclosure, the memory may store a guide list having various locations, rotation values, and the like, and the processor may display the guide based on the guide list. For example, referring to FIG. 5B, after displaying the first guide 502, the processor may select and display the second guide 504 of guides included in the guide list to obtain a part of a right region of the fingerprint of the finger.

FIG. 6A illustrates a fingerprint sensing region 122 c of a rectangular shape and first to third guides 502, 504, and 506 displayed on the fingerprint sensing region 122 c, according to an embodiment of the present disclosure. FIG. 6B illustrates a four-square fingerprint sensing region 122 c and first to third guides 502, 504, and 506 displayed on the fingerprint sensing region 122 c, according to an embodiment of the present disclosure. FIG. 6C illustrates a third guide displayed on a display such that fingerprint information that is not included in first fingerprint information and second fingerprint information is obtained. Embodiments illustrated in FIGS. 6A to 6C may be examples of operation 409 for setting an additional guide (e.g., the third guide 506).

Referring to FIGS. 6A and 6B, a processor may allow the display 106 to display a third guide 506 based on a size of the fingerprint sensor 122 a or a shape of the fingerprint sensor 122 a. Since the fingerprint sensor 122 a is a rectangular form in FIG. 6A, the processor may allow the display 106 to sequentially display the first to third guides 502, 504, and 506 in a region aligned in a second direction on the fingerprint sensing region 122 c. The first to third guides 502, 504, and 506 are illustrated in FIG. 6A as being sequentially displayed in the order of the first to third guides 502, 504, and 506 in the region aligned in the second direction on the fingerprint sensing region 122 c. However, the first to third guides 502, 504, and 506 may be sequentially displayed in a region aligned in a fourth direction on the fingerprint sensing region 122 c.

Referring to FIG. 6B, the first guide 502 to third guide 506 may be sequentially displayed in a region aligned in a third direction on the fingerprint sensing region 122 c. Since the fingerprint sensor 122 a is the rectangular form in FIG. 6B, the first to third guides 502, 504, and 506 may be sequentially displayed in a region aligned in the first direction, the second direction, or the fourth direction on the fingerprint sensing region 122 c. In addition, if the sufficient fingerprint information is obtained because the fingerprint sensor 122 a is the rectangular form and the first guide 502 is displayed in the center region of the fingerprint sensing region 122 c, the second guide 504 and the third guide 506 may not be displayed.

According to an embodiment, the processor may make it possible to display the third guide 506 based on how much the first fingerprint information is the same as the second fingerprint information. Returning to FIG. 6A, a part in which the first fingerprint information is the same as the second fingerprint information may be a part of a right region of a fingerprint of a finger. Accordingly, to obtain a part of a left region of the fingerprint of the finger, the processor may allow the display 106 to display the third guide 506 in a region moving from the fingerprint sensing region 122 c in a second direction.

Referring to FIG. 6B, the part in which the first fingerprint information is the same as the second fingerprint information may be a part of a lower region of the fingerprint of the finger. Accordingly, to obtain a part of an upper region of the fingerprint of the finger, the processor may allow the display 106 to display the third guide 506 in a region moving from the fingerprint sensing region 122 c in a third direction.

Referring to FIG. 6C, the processor may display the third guide 506 in the display such that fingerprint information that is not included in the first fingerprint information and the second fingerprint information is obtained. For example, as illustrated in FIG. 6C, the processor may obtain a part of a right region of the fingerprint of the finger through the first guide 502, and may obtain a part of a left region of the fingerprint of the finger through the second guide 504. Accordingly, to obtain fingerprint information that is not included in the first fingerprint information and the second fingerprint information, the processor may display the third guide 506 in a region moving from the fingerprint sensing region 122 c in a first direction. If the third guide 506 is displayed, the processor may obtain a part of a lower region of the fingerprint of the finger through the third guide 506.

The third guide 506 is illustrated in FIG. 6C as being displayed in the region moving in the first direction of a fingerprint sensing region. However, the third guide 506 may be displayed in a region in the third direction. If the third guide 506 is displayed in the third direction, the processor may obtain a part of an upper region of the fingerprint of the finger. According to an embodiment of the present disclosure, the processor may obtain the entire fingerprint of the finger by displaying the third guide 506 such that the fingerprint information that is not included in the first fingerprint information and the second fingerprint information is obtained.

FIG. 7 illustrates a first non-overlapped region 122 c-1 and a second non-overlapped region 122 c-2, according to an embodiment of the present disclosure.

Referring to FIG. 7, a processor may obtain the first non-overlapped region 122 c-1 and the second non-overlapped region 122 c-2. The first non-overlapped region 122 c-1 may be the remaining region other than a region, in which the fingerprint sensing region 122 c overlaps the first guide 502, in the fingerprint sensing region 122 c. The second non-overlapped region 122 c-2 may be the remaining region other than a region, in which the fingerprint sensing region 122 c overlaps the second guide 504, in the fingerprint sensing region 122 c.

If the first non-overlapped region 122 c-1 and the second non-overlapped region 122 c-2 are obtained, the processor may obtain the length of the fingerprint based on the first non-overlapped region 122 c-1 and the second non-overlapped region 122 c-2. For example, the processor may allow the display 106 to display the first guide 502 in a region moving from the fingerprint sensing region 122 c in a second direction. If the first guide 502 is displayed in the region moving from the fingerprint sensing region 122 c in the second direction, the processor may obtain a left fingerprint region of a finger, and the first non-overlapped region 122 c-1 may be formed in a region moving from a center of the fingerprint sensing region 122 c in a fourth direction. Unlike the first guide 502, the processor may allow the display 106 to display the second guide 504 in the region moving from the fingerprint sensing region 122 c in the fourth direction. If the display 106 displays the second guide 504 in the region moving from the fingerprint sensing region 122 c in the fourth direction, the processor may obtain a right fingerprint region of the fingerprint of the finger, and the second non-overlapped region 122 c-2 may be formed in a region moving from a center of the fingerprint sensing region 122 c in the second direction.

If the first non-overlapped region 122 c-1 and the second non-overlapped region 122 c-2 are formed on the fingerprint sensing region 122 c, the processor may obtain a length of the fingerprint based on a length of the first non-overlapped region 122 c-1 and a length of the second non-overlapped region 122 c-2. For example, in FIG. 7, the length of the fingerprint sensing region 122 c may be 8 mm, the length of the first non-overlapped region 122 c-1 may be 2 mm, and the length of the second non-overlapped region 122 c-2 may be 1.5 mm Since the length of the fingerprint sensing region 122 c is 8 mm and the length of the first non-overlapped region 122 c-1 is 2 mm, the length of the left fingerprint region of the finger may be 6 mm (8 mm−2 mm=6 mm). Since the length of the fingerprint sensing region 122 c is 8 mm and the length of the second non-overlapped region 122 c-2 is 1.5 mm, the length of the right fingerprint region of the finger may be 6.5 mm (8 mm−1.5 mm=6.5 mm). Accordingly, a width of the fingerprint may be 12.5 mm that is a sum of the length of the left fingerprint region and the length of the right fingerprint region.

In FIG. 7, an embodiment obtaining the width of the fingerprint is illustrated. However, the height of the fingerprint may be obtained by using the embodiment illustrated in FIG. 7. In addition, an area of the fingerprint may be obtained by using the width and the height of the fingerprint.

FIG. 8 is a flowchart for describing release of a lock state of an electronic apparatus, according to an embodiment of the present disclosure. FIG. 9 illustrates the display 106 in which a fingerprint authentication guide 900 is displayed, according to an embodiment of the present disclosure.

Referring to FIGS. 8 and 9, in operation 801, the electronic apparatus 100 may enter a state for authenticating a fingerprint. For example, the state for authenticating the fingerprint may be a state where a display recognizes the fingerprint in the lock state to release the lock state.

If the electronic apparatus 100 enters a state for authenticating the fingerprint, in operation 803, the processor may allow the display 106 to display a fingerprint authentication guide 900. The fingerprint authentication guide 900 is illustrated in FIG. 9 as being displayed on the display 106 to release a screen lock state. However, the fingerprint authentication guide 900 may be displayed on the display 106 when a financial transaction or the like is made.

If the fingerprint authentication guide 900 is displayed on the display 106, in operation 805, the processor may obtain the fingerprint information for authentication. In operation 807, the processor may perform user authentication. For example, the processor may compare the fingerprint information registered through a process of FIG. 4 with the obtained fingerprint information. If the obtained fingerprint information corresponds to the fingerprint information registered in advance, in operation 809, the processor may release a lock state. Otherwise, the processor may maintain the lock state in operation 811.

FIG. 10 illustrates a view in which fingerprint information including preset minutiae is displayed, and in which the fingerprint authentication guide 900 is displayed at a location of a guide obtaining the fingerprint information according to an embodiment of the present disclosure. An embodiment illustrated in FIG. 10 may be an example of operation 803 described in FIG. 8.

Referring to FIG. 10, the processor may obtain fingerprint information, which includes preset minutiae 1002, of first fingerprint information and second fingerprint information. For example, the preset minutiae 1002 may be minutiae that are at the center of the fingerprint. As illustrated in FIG. 10, the first fingerprint information obtained through the first guide 502 may include the minutiae 1002 that is at the center of the fingerprint. On the other hand, the second fingerprint information obtained through the second guide 504 may not include the minutiae 1002 that is at the center of the fingerprint. Accordingly, in FIG. 10, the fingerprint information including the preset minutiae 1002 may be the first fingerprint information.

If the fingerprint information including the preset minutiae 1002 is obtained, the processor may obtain a location at which a guide obtaining the fingerprint information is displayed on the display 106. If the location is obtained, the processor may allow the display 106 to display the fingerprint authentication guide 900 at the location. In an example of FIG. 10, since the fingerprint information including the preset minutiae 1002 is the first fingerprint information, the processor may allow the display 106 to display the fingerprint authentication guide 900 at a location at which the first guide 502 is displayed.

Unlike the embodiment illustrated in FIG. 10, the fingerprint authentication guide 900 may be displayed at the location of the guide where the fingerprint information, the number of minutiae of which is great, is obtained. Furthermore, the fingerprint authentication guide 900 may be displayed at the location of the guide where the fingerprint information, the distribution of minutiae of which is wide, is obtained. Moreover, the fingerprint authentication guide 900 may be displayed at the location of the guide where the fingerprint information including a middle region of the fingerprint is obtained. According to an embodiment of the present disclosure, a fingerprint recognition rate may increase by displaying the guide based on the fingerprint information.

FIG. 11 is a flowchart for describing that the second guide 504 is displayed on the display 106 in the case where a finger touches a location different from the first guide 502, according to an embodiment of the present disclosure. FIG. 12 is a view which guides a finger to touch a center of the fingerprint sensing region 122 c by displaying the second guide 504 at a location different from the first guide 502, according to an embodiment of the present disclosure.

Referring to FIG. 11, in operation 1101, a processor may set the fingerprint sensing region 122 c on the display 106, and may display the first guide 502 such that the display 106 at least partly overlaps the fingerprint sensing region 122 c. If the finger touches the display 106, in operation 1103, the processor may obtain a contact region 1202 in which the finger touches the display 106. The contact region 1202 may at least partly overlap the first guide 502, or there may be no region in which the contact region 1202 overlaps the first guide 502.

In operation 1105, the processor may allow the display 106 to display the second guide 504 based on a location of the first guide 502 and a location of the contact region 1202. For example, the processor may obtain a spaced distance between the first guide 502 and the contact region 1202. The spaced distance may be a distance from a center of the first guide 502 to a center of the contact region 1202. If the spaced distance is obtained, after moving the second guide 504 from the center of the fingerprint sensing region 122 c by the spaced distance, the processor may display the second guide 504 on the display 106. If the second guide 504 is displayed on the display 106, in operation 1107, the processor may obtain fingerprint information by using the second guide 504.

Referring to FIG. 12, a user may touch a location, which is different from a location where the first guide 502 is displayed, with his/her finger 200. In FIG. 12, the user may touch a location, which moves from the first guide 502 in a right direction by 8 mm, with the finger 200. The location that the finger 200 touches may vary depending on a method in which the user grips the electronic apparatus 100, a form of his/her hand, or the like.

If the spaced distance (e.g., 8 mm) between the first guide 502 and the contact region 1202 is obtained, after moving the second guide 504 from the center of the fingerprint sensing region 122 c by 8 mm, the processor may output the second guide 504 on the display 106. If the second guide 504 is displayed after moving the second guide 504 from the center of the fingerprint sensing region 122 c by 8 mm, the contact region 1202 may be formed in the center of the fingerprint sensing region 122 c. According to an embodiment of the present disclosure, a fingerprint recognition rate may increase by displaying a guide based on habits of the user, or the like.

The embodiment illustrated in FIGS. 11 to 12 may be applied to both an embodiment registering a fingerprint and an embodiment authenticating the fingerprint. Referring to FIG. 12, in a process of registering a fingerprint, the user may touch a location different from a location of the first guide 502 with the finger 200. If the user touches a location different from a location of the first guide 502 with the finger 200, the processor may not obtain the fingerprint information. Accordingly, the processor may obtain the spaced distance between the first guide 502 and the contact region 1202. After moving the second guide 504 from the center of the fingerprint sensing region 122 c by the spaced distance, the processor may display the second guide 504. If the second guide 504 is displayed after being spaced apart from the center of the fingerprint sensing region 122 c, the user may touch the center of the fingerprint sensing region 122 c with the finger 200. The processor may obtain the second fingerprint information and may store the second fingerprint information in the memory 118.

Unlike the above-described example, in a process of authenticating a fingerprint, the user may touch a location different from a location of a guide with the finger 200. If the user touches a location different from the location of the guide with the finger 200, fingerprint authentication is impossible. Accordingly, the processor may display the second guide 504 on the display 106 by applying the spaced distance, which is obtained in the process of registering the fingerprint, between the first guide 502 and the contact region 1202. If the second guide 504 is displayed after being spaced apart from the center of the fingerprint sensing region 122 c, the user may touch the center of the fingerprint sensing region 122 c with the finger 200. The processor may obtain the second fingerprint information and may compare the first fingerprint information with the second fingerprint information. If the first fingerprint information is the same as the second fingerprint information, the processor may release a lock state.

The directions (e.g., first, second, third, and fourth directions) described in FIGS. 1 to 5A to 5E, 6A to 6C, and 7 to 12 may be provided as four directions for convenience of description. However, the directions may be certain directions on a display with respect to a location of a fingerprint sensing region.

FIG. 13 illustrates an electronic device in a network environment system, according to an embodiment of the present disclosure.

Referring to FIG. 13, according to an embodiment, an electronic device 1301, a first electronic device 1302, a second electronic device 1304, or a server 1306 may be connected each other over a network 1362 or a short range communication 1364. The electronic device 1301 may include a bus 1310, a processor 1320, a memory 1330, an input/output interface 1350, a display 1360, and a communication interface 1370. According to an embodiment, the electronic device 1301 may not include at least one of the above-described elements or may further include other element(s).

For example, the bus 1310 may interconnect the above-described elements 1310 to 1370 and may include a circuit for conveying communications (e.g., a control message and/or data) among the above-described elements.

The processor 1320 may include one or more of a CPU, an AP, or a CP. For example, the processor 1320 may perform an arithmetic operation or data processing associated with control and/or communication of at least other elements of the electronic device 1301.

The memory 1330 may include a volatile and/or nonvolatile memory. For example, the memory 1330 may store instructions or data associated with at least one other element(s) of the electronic device 1301. According to an embodiment, the memory 1330 may store software and/or a program 1340. The program 1340 may include, for example, a kernel 1341, a middleware 1343, an application programming interface (API) 1345, and/or an application program (or “an application”) 1347. At least a part of the kernel 1341, the middleware 1343, or the API 1345 may be referred to as an “operating system (OS)”.

For example, the kernel 1341 may control or manage system resources (e.g., the bus 1310, the processor 1320, the memory 1330, and the like) that are used to execute operations or functions of other programs (e.g., the middleware 1343, the API 1345, and the application program 1347). Furthermore, the kernel 1341 may provide an interface that allows the middleware 1343, the API 1345, or the application program 1347 to access discrete elements of the electronic device 1301 so as to control or manage system resources.

The middleware 1343 may perform, for example, a mediation role such that the API 1345 or the application program 1347 communicates with the kernel 1341 to exchange data.

Furthermore, the middleware 1343 may process task requests received from the application program 1347 according to a priority. For example, the middleware 1343 may assign the priority, which makes it possible to use a system resource (e.g., the bus 1310, the processor 1320, the memory 1330, or the like) of the electronic device 1301, to at least one of the application program 1347. For example, the middleware 1343 may process the one or more task requests according to the priority assigned to the at least one, which makes it possible to perform scheduling or load balancing on the one or more task requests.

The API 1345 may be, for example, an interface through which the application program 1347 controls a function provided by the kernel 1341 or the middleware 1343, and may include, for example, at least one interface or function (e.g., an instruction) for a file control, a window control, image processing, a character control, or the like.

The input/output interface 1350 may play a role, for example, of an interface which transmits an instruction or data input from a user or another external device, to other element(s) of the electronic device 1301. Furthermore, the input/output interface 1350 may output an instruction or data, received from other element(s) of the electronic device 1301, to a user or another external device.

The display 1360 may include, for example, a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 1360 may display, for example, various contents (e.g., a text, an image, a video, an icon, a symbol, and the like) to a user.

A method for operating an electronic apparatus, the method comprising: if the electronic apparatus enters a state for registering a fingerprint of a finger, setting a fingerprint sensing region at a location, corresponding to a location a fingerprint sensor is disposed, on a display; displaying a first guide on the display such that the first guide at least partly overlaps the fingerprint sensing region; obtaining first fingerprint information through the fingerprint sensing region if the finger touches the first guide; displaying a second guide on the display such that the second guide at least partly overlaps the fingerprint sensing region; and obtaining second fingerprint information through the fingerprint sensing region if the finger touches the second guide.
 15. The method of claim 14, wherein the displaying of the second guide includes: displaying the second guide on the display based on one or more of a location of the first guide, an area of a region in which the first guide overlaps the fingerprint sensing region, or the first fingerprint information.
 16. The method of claim 14, wherein the displaying of the second guide includes: obtaining a region missed in the first fingerprint information; and displaying the second guide on the display based on the missed region.
 17. The method of claim 14, further comprising: displaying a third guide on the display based on one or more of a size of the fingerprint sensor, a shape of the fingerprint sensor, or how similar the first fingerprint information is to the second fingerprint information.
 18. The method of claim 14, further comprising: obtaining a first non-overlapped region that is a region other than a region in which the fingerprint sensing region overlaps the first guide in the fingerprint sensing region; and obtaining a second non-overlapped region that is a region other than a region in which the fingerprint sensing region overlaps the second guide in the fingerprint sensing region.
 19. The method of claim 18, further comprising: obtaining a length of the fingerprint based on the first non-overlapped region and the second non-overlapped region.
 20. The method of claim 14, further comprising: displaying a fingerprint authentication guide on the display if the electronic apparatus enters a state for authenticating the fingerprint.
